AUTOMOBILE BUMPER BRACKET.

Application led February 12, 1924. Serial No. 692,240.

To @ZZ whom t may concern.'

Be it known that GEORGE F. Kenn, a citizen of the United States, and resident of Fairfield, in the county of Fairfield and State of Connecticut, has invented certain new and useful Improvements in Automobile Bumper Brackets, of which the following is a specification.

My present invention relates to automobile bumpers and more particularly to an improved form of bracket adapted for attachment to the rear end of an automobile chassis frame and designed particularly for carrying what are commonly known as spring bumper bars.

The present styles of automobiles obviously include many different rear end structures ot chassis frames, bodies, springs, tire and trunk racks, which make it extremely diiiicult in many cases to attach spring bumpers to the rear of an automobile in a Way to have them properly positioned to protect the car, trunk racks, etc., and still look well.

rIhe object of the invention is to generally improve upon bumper brackets of this class and more particularly to provide a universal form of bracket which is adapted for attachment to many different styles and makes of cars, and including various forms ot rear end structures.

I find that the chassis constructions of many of the higher priced cars include a pair of rear end spring hangers, which are usually formed integral with the side bar members of the chassis frame. These springs vary somewhat in length and likewise in shape, the more common formsbeing curved downward more or less, terminating in an eye to which Athe spring ends are hingedly connected.

My bracket has been particularly designed with a view of attachment to these rear end spring hangers and are adjustable to accom-- modate hangers of this type having different curves whereby the bumper bars may be positioned horizontally and at the desired distance from the ground. The invention is further adapted to the provision of either single or double spring bar bumpers.

lith these and other objects in view the invention resides and consists in the construction and novel combination and arrangement o parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to wit-hout departure from the spirit or sacriiicing any of the advantages of the invention.

Similar characters of reference denote like or corresponding parts throughout the several figures of the accompanying drawings forming a part of this specification, and upon which,

Fig. l shows a perspective view of one of my bumper brackets attached to one of a pair of rear end hangers ot an automobile chassis frame;

Fig. Q shows a plan view ot the opposite bracket, attached to a hanger., and having a portion oi" a spring bumper bar supported therein;

3 is a similar plan view of the coacting bracket attached to the opposite hanger, and supporting the opposite end portion of a bumper bar;

Fig. 4: shows a further plan view of the bracket and hanger shown in Fig. 2, the bumper arm being in a reversed position to agree with that shown in Fig. 1

Fig. 5 illustrates a side elevation of the bracket, on an enlarged scale, as seen from the right side of Fig. 3, and in position as if attached to a spring hanger.

Fig. 6 shows aside elevation as seen from the opposite side of Fig. 5 and illustrates a bracket adapted to carry a pair or' bumper bars; and

Fig. 7 is an end View of the bumper arm and bracket member to which it is attached, as seen from the right of Fig. 6.

As designed my improved bracket is made up of three principal parts, suitably connected together and provided with means for attachment lto the rear end of the chassis frame or' an automobile, and for the support of such spring bumperl bars as they are designed to carry. Two of the said parts included in the bracket are adjustably :onnected together and are adapted to be adjustably attached to the rear spring hanger ot a chassis frame. The bumper arm member of the bracket .is disposed forward horizontally and may be constructed to support either one or two spring bumper bars. These parts are susceptible of being assembled and attached in several ways, better to accommodate the rear end construction of the particular car to which it is to be attached, or what is more frequently the case to accommodate and build around the tire rack or trunk rack structure on the rear of said car.

Referring in detail to the characters of reference marked upon the drawings, A and B represent the two rear end extended portions of a chassis frame, sometimes referred to as spring hangers. There are usually two of these extensions on a car that extend rearwardly and downwardly in more or less of a curved manner and serve for the attachment of the rear end springs. I apply one of my novel brackets to each of thesehangers in a way to support the two end portions of a spring bumper bar on the rear of an automobile.

Ihe several parts of the bumper bracket, for the two sides, are alike in construction, except that the members 8 and 9 are made up in rights and lefts, see Figs. Qand 3, whereas the supporting arms l() are not, but are made. up in two styles to accommodate either a single bumper bar, see F ig. 5, or a double bumper bar, see Fig. 6. The supporting arm lO is reversible and can be deflected outward, as shown in Figs. 2 and 3, or inward, see Figs. l and 4. IVhile the bracket is made up in rights and lefts, yet it will be apparent that the position of the two brackets may be reversed. That is to say thel bracket shown in Fig. Q, can be placed on the hanger of Fig. 3 or the bracket of Fig. 3 may be placed on the hanger of Fig. 2, to better accommodate the particular construction vof the rear end of the automobile upon which it is to be placed. The member 8 of the bracket includes a body portion having a downwardly disposed flange 1l, an upwardly disposed flange l2 and an outwardly disposed Aear 12E. This ear and the main body are provided with aligned holes M lll to receive the threaded ends 15 of a yoke 16 foi-'attachment to the spring hanger. rI`he under edge portion of the member 8 is provided with a series of curved serrations or teeth as at 17 to better engage the top edge of hangers A and B in a manner to form a positive grip and prevent the bracket member from slipping and coming loose. The threaded ends 15 of the yoke are provided with nuts 18 for clampingl the yoke and member to the hanger. In practice this member 8 is firsty applied to the curved spring hanger and the other member 9 is connected later. This member 8 is thus positioned and secured so that its bolt holes 19-19 are in horizontal alignment and its bottom edge rests upon the shackle or spring bolt 2O of the spring hangers to which it is attached and bolts 19a serve to clamp the bumper arm l0 to the downwardly disposed flange ll of the member 8 thus making the arm reversible as before suggested. Y

The upwardly disposed iiange l2 is provided with a hole to receive a clamping bolt 2l and by means of which the bracket member 9 is adjustably connected therewith. I preferably provide a libre washer 22 upon the bolt between the adjacent surfaces of the said parts 8 and 9 in order to more rigidly clamp them together. This member 9 further includcs oppositely disposed ears 23 having aligned holes 24 therein to receive a second yoke 25 adapted to engage the hanger and having threaded portions to pass through the holes 24 of ears 23 and provided with nuts 2G for clamping the bracket member and yoke to the spring hangers A or B.

The under side of the forward end of the member 8 also includes a series of curved teeth or seri-ations as at 27 to better grip the.

top side of the hangers. It will thus be seen that the members 8 and 9 are adjustably connected together and each clamped to a hanger in a manner to be firmly supported and in a way to dispose the bottom edge portion of the member 8 in a horizontal position to properly support the bumper arm in y a like manner. The adjustable connection 2l between the parts 8 and 9 better adapts the bracket to be attached to spring hangers of different shapes and curves. y

lrIhe bumper arm 10 is provided upon its forward endy with a vertically disposed face 28 in which is formed one or more pockets 29 to reeeivethe spring bumper 30; rIhis face is further provided with screw holes for the attachment of the clamping plate 31 by means of the screws 32 and by means of which the aforesaid bumper bar is attached.

Having thus described my .invention what I claim and desire to secure by Letters Patent is: v

l. An automobile bumper bracketI for attachment to the frame end of an automobile comprising a parir of bracket members having projectedfiange portions, one of the pair forming an attaching face for a bumper bar and the other a fixed member of an adjustable connection, a clamping bolt for securing one of the bracket members to a chassis frame, one of the bracket members being hingedly connected to the other member, and a bumper bar secured to the first named bracket member.
